Notes:
kg = kilogram
PCP = Pentachlorophenol
WTP = water treatment plant

Pentachlorophenol mass removed estimated from difference between water treatment plant influent and effluent PCP concentrations and weekly measured water treatment plant inflow rate.

Pentachlorophenol percent removed estimated from difference between water treatment plant influent and effluent PCP concentrations.
